In order to maintain the appearance of your
vehicle, it is important to take proper care of it.
To protect the paint surface, wash your vehicle
as soon as you can:
● after a rainfall to prevent possible damage
from acid rain
● after driving on coastal roads
● when contaminants such as soot, bird drop-
pings, tree sap, metal particles or bugs get
on the paint surface
● when dust or mud builds up on the surface
Whenever possible, store or park your vehicle
inside a garage or in a covered area.
When it is necessary to park outside, park in a
shady area or protect the vehicle with a body
cover.
Be careful not to scratch the paint surface when
putting on or removing the body cover.
WASHING
Wash dirt off the vehicle with a wet sponge and
plenty of water. Clean the vehicle thoroughly
using a mild soap, a special vehicle soap or
general purpose dishwashing liquid mixed with
clean, lukewarm (never hot) water.
CAUTION
● Do not use car washes that use acid in the
detergent. Some car washes, especially
brushless ones, use some acid for cleaning.
The acid may react with some plastic vehicle
components, causing them to crack. This
could affect their appearance, and also could
cause them not to function properly. Always
check with your car wash to confirm that acid
is not used.
● Do not wash the vehicle with strong house-
hold soap, strong chemical detergents,
gasoline or solvents.
● Do not wash the vehicle in direct sunlight or
while the vehicle body is hot, as the surface
may become water-spotted.
● Avoid using tight-napped or rough cloths,
such as washing mitts. Care must be taken
when removing caked-on dirt or other for-
eign substances so the paint surface is not
scratched or damaged.
Rinse the vehicle again with plenty of clean
water.
Inside flanges, seams and folds on the doors,
hatches and hood are particularly vulnerable to
the effects of road salt. Therefore, these areas
must be regularly cleaned. Make sure that the
drain holes in the lower edge of the door are
open. Spray water under the body and in the
wheel wells to loosen the dirt and wash away
road salt.
Avoid leaving water spots on the paint surface
by using a damp chamois to dry the vehicle.
WAXING
Regular waxing protects the paint surface and
helps retain new vehicle appearance. Polishing
is recommended to remove built-up wax residue
and to avoid a weathered appearance before
reapplying wax.
An INFINITI dealer can assist you in choosing
the proper product.
● Wax your vehicle only after a thorough wash-
ing. Follow the instructions supplied with
the wax.
● Do not use a wax containing any abrasives,
cutting compounds or cleaners that may
damage the vehicle finish.
Machine compound or aggressive polishing on
a base coat/clear coat paint finish may dull the
finish or leave swirl marks.

-------------------------------------------------------------------------------------------------------------------------------------------------------------
REMOVING SPOTS
Remove tar and oil spots, industrial dust, in-
sects, and tree sap as quickly as possible from
the paint surface to avoid lasting damage or
staining. Special cleaning products are avail-
able at an INFINITI dealer or any automotive
accessory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This will
prevent dirt and salt from building up and
causing the acceleration of corrosion on the
underbody and suspension. Before the winter
period and again in the spring, the underseal
must be checked and, if necessary, re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows, do
not use sharp-edged tools, abrasive cleaners or
chlorine-based disinfectant cleaners. They
could damage the electrical conductors, radio
antenna elements or rear window defroster
elements.
ALUMINUM ALLOY WHEELS
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
CAUTION
Follow the directions below to avoid staining or
discoloring the wheels:
● Do not use a cleaner that uses strong acid or
alkali contents to clean the wheels.
● Do not apply wheel cleaners to the wheels
when they are hot. The wheel temperature
should be the same as ambient temperature.
● Rinse the wheel to completely remove the
cleaner within 15 minutes after the cleaner is
applied.
CHROME PARTS
Clean chrome parts regularly with a non- abra-
sive chrome polish to maintain the finish.
TIRE DRESSING
INFINITI does not recommend the use of tire
dressings. Tire manufacturers apply a coating
to the tires to help reduce discoloration of the
rubber. If a tire dressing is applied to the tires,
it may react with the coating and form a com-
pound. This compound may come off the tire
while driving and stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
● Use a water-based tire dressing. The coating
on the tire dissolves more easily with an
oil-based tire dressing.
● Apply a light coat of tire dressing to help
prevent
it
from
entering
the
tire
tread/grooves (where it would be difficult to
remove).
● Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is com-
pletely removed from the tire tread/grooves.
● Allow the tire dressing to dry as recom-
mended by tire dressing manufacturer.

Occasionally remove loose dust from the inte-
rior trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl
and leather surfaces with a clean, soft cloth
dampened in mild soap solution, then wipe
clean with a dry soft cloth.
Regular care and cleaning is required in order to
maintain the appearance of the leather.
Before using any fabric protector, read the
manufacturer’s recommendations. Some fabric
protectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water, to clean
the meter and gauge lens.
CAUTION
● Never use benzine, thinner, or any similar
material.
● Small dirt particles can be abrasive and dam-
aging to the leather surfaces and should be
removed promptly. Do not use saddle soap,
car waxes, polishes, oils, cleaning fluids,
solvents, detergents or ammonia-based
cleaners as they may damage the leather’s
natural finish.
● Only use fabric protectors approved by
INFINITI.
● Do not use glass or plastic cleaner on meter
or gauge lens covers. It may damage the lens
cover.
POWER WINDOW SWITCH FINISHER
(Sedan)
Wipe the power window switch finisher surfaces
with a clean soft cloth dampened in a mild soap
solution, then wipe it clean with a dry, soft
cloth.
Some cleaners contain chemicals that may
stain or peel off the surface. Before using any
cleaner, contact an INFINITI dealer for recom-
mendations.
Regular care and cleaning is required in order to
maintain the appearance of the power finisher
surfaces.

FLOOR MATS
The use of INFINITI floor mats can extend the life
of your vehicle carpet and make it easier to
clean the interior.
No matter what mats are
used, be sure they are fitted for your vehicle and
are properly positioned in the footwell to pre-
vent interference with pedal operation. Mats
should be maintained with regular cleaning and
replaced if they become excessively worn.
Floor mat positioning aid
This model includes front floor mat brackets to
act as floor mat positioning aid. INFINITI floor
mats have been specially designed for your
vehicle model. The front floor mats have grom-
met holes in them. To install, simply position
the mat by placing the floor mat bracket
through the floor mat grommet hole while cen-
tering the mat in the floor pan contour.
Periodically check to make certain that the mats
are properly positioned.
SEAT BELTS
The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solu-
tion. Allow the belts to dry completely before
using them.
See “SEAT BELTS” in the “1. Safety — Seats,
seat belts and supplemental restraint system”
section.
WARNING
Do not allow wet seat belts to roll up in the
retractor. NEVER use bleach, dye, or chemical
solvents to clean the seat belts, since these
materials may severely weaken the seat belt
webbing.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
● The accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas.
● Damage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic accidents.
ENVIRONMENTAL FACTORS INFLUENCE
THE RATE OF CORROSION
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. Wet floor coverings will not dry completely
inside the vehicle, and should be removed for
drying to avoid floor panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas where
the temperatures stay above freezing where
atmospheric pollution exists, or where road salt
is used.
Temperature
A temperature increase will accelerate the rate
of corrosion to those parts which are not well
ventilated.
Air pollution
Industrial pollution, the presence of salt in the
air in coastal areas, or heavy road salt use will
accelerate the corrosion process. Road salt will
also accelerate the disintegration of paint sur-
faces.
TO PROTECT YOUR VEHICLE FROM
CORROSION
● Wash and wax your vehicle often to keep the
vehicle clean.
● Always check for minor damage to the paint
and repair it as soon as possible.
● Keep drain holes at the bottom of the doors
open to avoid water accumulation.
● Check the underbody for accumulation of
sand, dirt or salt. If present, wash with water
as soon as possible.
CAUTION
● NEVER remove dirt, sand or other debris from
the passenger compartment by washing it
out with a hose. Remove dirt with a vacuum
cleaner or broom.
● Never allow water or other liquids to come in
contact with electronic components inside
the vehicle as this may damage them.
Chemicals used for road surface deicing are
extremely corrosive. They accelerate corrosion
and deterioration of underbody components
such as the exhaust system, fuel and brake
lines, brake cables, floor pan and fenders.
In winter, the underbody must be cleaned peri-
odically.
For additional protection against rust and cor-
rosion, which may be required in some areas,
consult an INFINITI dealer.

Your new INFINITI has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your IN-
FINITI’s fine mechanical condition, as well as its
emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance care. You are a vital link in the
maintenance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “INFINITI Service and
Maintenance Guide”. You must refer to that
guide to ensure that necessary maintenance is
performed on your INFINITI at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-to-
day operation. They are essential for proper
vehicle operation. It is your responsibility to
perform these procedures regularly as pre-
scribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
an INFINITI dealer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your ve-
hicle appears to malfunction, have the systems
checked and serviced by an INFINITI dealer.
INFINITI technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips, and in-dealership information systems.
They are completely qualified to work on
INFINITI vehicles
before work begins.
You can be confident that an INFINITI dealer’s
service department performs the best job to
meet the maintenance requirements on your
vehicle — in a reliable and economical way.
During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have an
INFINITI dealer do it promptly. In addition, you
should notify an INFINITI dealer if you think that
repairs are required.
When performing any checks or maintenance
work, see “MAINTENANCE PRECAUTIONS” later
in this section.
EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following items
with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood: Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary latch
keeps the hood from opening when the primary
latch is released.

When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking the
tires, make sure no wheel nuts are missing, and
check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
7,500 miles (12,000 km). If your vehicle is
equipped with different sized tires in the front
and rear, tires cannot be rotated.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If nec-
essary, adjust the pressure in all tires, includ-
ing the spare, to the pressure specified. Check
carefully for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS) trans-
mitter components: Replace the TPMS transmit-
ter grommet seal, valve core and cap when the
tires are replaced due to wear or age.
Tire, wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the
INFINITI Warranty Information Booklet.
Windshield: Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.
Accelerator pedal: Check the pedal for smooth
operation and make sure the pedal does not
catch or require uneven effort. Keep the floor
mat away from the pedal.
Automatic transmission P (Park) mechanism: On
a fairly steep hill, check that your vehicle is held
securely with the selector lever in the P (Park)
position without applying any brakes.
Brake pedal: Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down
further than normal, the pedal feels spongy or
the vehicle seems to take longer to stop, see an
INFINITI dealer immediately. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake opera-
tion regularly. The vehicle should be securely
held on a fairly steep hill with only the parking
brake applied. If the parking brake needs ad-
justed, see an INFINITI dealer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head

restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Steering wheel: Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that all
warning lights and chimes are operating prop-
erly.
Windshield defroster: Check that the air comes
out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that the
wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or un-
der severe condition require frequent checks of
the battery fluid level.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil to
drain back into the oil pan.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI dealer. (See
“PRECAUTIONS WHEN STARTING AND DRIVING”
in the “5. Starting and driving” section for
exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from
the air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes are
evident, check for the cause and have it cor-
rected immediately.
Power steering fluid level* and lines: Check the
level when the fluid is cold, with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
● Park the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. For
manual transmission models, move the shift
lever to N (Neutral). For automatic transmis-
sion models, move the selector lever to P
(Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position.
● If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
● It is advisable to secure or remove any loose
clothing and remove any jewelry, such as
rings, watches, etc. before working on your
vehicle.
● Always wear eye protection whenever you
work on your vehicle.
● If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
● Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery.
● Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● The fuel filter or fuel lines should be serviced
by an INFINITI dealer because the fuel lines
are under high pressure even when the en-
gine is off.
CAUTION
● Do not work under the hood while the engine
is hot. Turn the engine off and wait until it
cools down.
● Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able.
(See
“OWNER’S
MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
